Definitions

• the present disclosure relates to assets for use in process and manufacturing plants including an integral radio frequency identification (RFID) module. More specifically, the present disclosure relates to plant assets having a RFID module configured to communicate asset specific information to an associated reader.
• RFID radio frequency identification
• NFC Near field communications
• RFID involves the hardware known as readers (also known as interrogators), and transponders (also known as tags or labels), as well as RFID software or RFID middleware.
• Inductively coupled NFC - RFID systems are based on a transformer-type coupling between a primary coil in a reader and a secondary coil in a transponder. Typically, coupling occurs when the distance between the corresponding coils is within approximately 0.16 ft., such that the transponder is located in the near field of the reader's antenna. Electrical energy is transmitted from the reader to the transponder via magnetic coupling between the primary coil in the reader and the secondary coil in the transponder.
• RFID can be either passive (using no battery), active (i.e. the transponder has an on-board battery and broadcasts or beacons a signal) or battery assisted passive (BAP) which incorporates a small battery on board that is activated when a transponder is proximate a reader.
• BAP battery assisted passive
• Some RFID transponders are read from several meters away and beyond the line of sight of the reader.
• NFC - RFID is related to systems that rely on a transponder being in close proximity to a corresponding reader. When a resonant transponder is placed within the magnetic alternating field of the reader's antenna (i.e. the self-resonant frequency of the transponder corresponds with the transmission frequency of the reader), the transponder draws energy from the magnetic field generated by the reader.
• This additional power consumption can be measured as voltage drop at the internal resistance in the reader' s antenna through the supply current to the reader's antenna.
• Switching on and off of a load resistance at the transponder's antenna therefore effects voltage changes at the reader's antenna and thus has the effect of an amplitude modulation of the antenna voltage by the remote transponder.
• this data can be transferred from the transponder to the reader. This type of data transfer is called load modulation.

• a local database for keeping device records up to date employs a near field communications interface. This configuration assists customers to maintain equipment records.
• a NFC system may be provided for storing maintenance history, inspection history, and calibration history of assets.
• a NFC system may also be used for equipment checks and audits, such as for example, to get bolt torques, lubrication requirements, etc.
• a NFC system may, for example, be used in remote locations where access to databases or records is limited (e.g., oil patch).
• a NFC system may provide a physical link for paperwork to the device itself, such as for example, provide a record of post weld heat treat times.
• a passive NFC system may be configured to provide a zero power wireless link to an associated processor, or processors.
• a NFC system may be employed to retrieve, for example, instrument state variables (ref, tvl, press), alerts, and/or device information (FW rev., S/N, last calibration date).
• a semi-passive (i.e. the associated asset data module provides a power source) NFC system may be configured as a data historian.
• a NFC interface may be configured to provide interface for detached field devices. Plant- wide, networked infrastructure is not required with NFC systems.
• a NFC system may be used to identify counterfeit or unapproved parts.
• a NFC system is employed to match an auxiliary part to a valve assembly and may be used to manage parts on large construction projects.
• a NFC system may be configured as a replacement for licensing dongles where no USB connections are available.
• a NFC system may provide temporary secure memory for assets.
• a NFC system assists in finding parts quickly in a boneyard, staging area, or in inventory.
• NFC Network-Field-Field-Field-Field-Field-Field-Field-Fi Protected Access
• a NFC system may be used to scan parts bins or pallets to find parts.
• RFID can see through cardboard shipping containers, therefore, there is no need to unpack assets for inspection.
• Employees may be tracked throughout a plant with RFID systems and used to locate employees in hazardous areas.
